Metric Halo SpectraFoo Version 1.5 - Manual (Page 25)

Changing the analysis depth
You can change the number of samples that SpectraFoo uses in its FFT analysis. Increasing the number of points
increases the frequency resolution of the analysis (it allows you to see narrower spectral features - especially on the
low end) but it tends to smear the high end in time and can lead to a de synchronization of the audio from the analy-
sis. Metric Halo recommends using either a 4096 pt or a 8192 pt FFT Analyzer depth for music production work.
Changing the analyzer depth is simple. Just select the desired depth from the Analyzer popup menu in the upper left
hand corner of the Analyzer Control & Routing window. The change take place automatically and instantly.
Configuring the routing matrix
Once you have selected your audio input path, you should configure the routing matrix to remove any ambiguity
from the process of monitoring your audio. If your audio path is two-channel the default configuration is probably
fine (Left Channel named Left, Right Channel named Right).
If you are using a multi-channel input path (such as the Korg 1212 I/O) The first step is to name the input channels.
SpectraFoo provides a mechanism for naming the input channels. To access this mechanism, simply click on the
small lock icon on the lower left hand corner of the Analyzer Control & Routing window. The window will expand
to show the M input channel names. It looks like this:
You can type the proper input channel names into the edit text areas. The key will move the input focus to the
next field. will move the input focus to the previous field.
